[0003] However, the loss of performance usually occurs gradually, so that the satisfaction with the product will gradually decrease until the workpiece is in fact replaced.
In some cases, equipment was mistakenly discarded before the workpiece was replaced

Embodiment Construction

[0010] figure 1 A motorized skin brush, generally indicated at 10, is shown. The motorized skin brush includes a handle 12 and a brush head 14 including a set of bristles 16 . A brush head having a set of bristles is typically easily replaceable. In operation, the powered skin brush includes a drive assembly including a motor and a rechargeable battery. The drive assembly drives the brush head assembly in a selected motion. One such motion is a vibration with an angle / amplitude of 7° and a frequency of 176 Hz. The drive assembly is controlled by a microprocessor which typically includes software and firmware for operating the device. Such devices are shown in more detail in US Patent Nos. 7,786,626 and 7,386,906, owned by the assignee of the present invention, the contents of which are incorporated herein by reference. As indicated above, the performance of skin brushes can degrade over time due to wear or other reasons. In the present invention, a microprocessor in the ...

Abstract

The compensating / performance regulation system includes a power skin brush having a handle, an oscillating brushhead workpiece and a drive system, wherein the brushhead workpiece has an RFID tag. An RFID reader is provided in the handle and is responsive to the RFID tag moving past the reader to produce an indication of use of the brushhead. A microprocessor calculates a value of actual use from the RFID information and uses stored information to determine the decline in performance from the calculated use. A compensating change in drive frequency or duty cycle of the drive signal is then determined by the microprocessor from stored information and transmitted to the drive system to maintain performance of the appliance.

Description

technical field [0001] The present invention relates generally to skin care devices, and more particularly to systems for compensating for degradation / reduction in performance of workpiece portions of such devices. Background technique [0002] Motorized skin care devices typically include a moving (usually vibrating) workpiece part, such as a brush / bristle part, also called a brush head. Brush parts age, wear or become dirty with time and use. Further, workpieces dispensed with consumable material gradually become depleted. These gradual physical artifacts result in degraded performance of the device, either due to dynamic performance changes that create differences in amplitude motion, or more directly due to changes in the properties of the brush / bristle itself, such as flexibility. It is usually intended to replace such brush artifacts when the performance of the device no longer meets certain criteria. [0003] However, the loss of performance usually occurs graduall...
